One of the best ways to get ripped off in coin collecting is to buy Chinese coins from someone you do not know. We know Baldwin's, the world-renowned numismatic dealer in London. The 1 mace and 4.4 candareens (20 cent) coin in our main picture comes from Baldwin's, and it sold for $2200 US dollars in a 2011 auction. Genuine 7 mace and 2 candareens (one dollar) coins are tremendously valuable, selling for tens of thousands of US dollars.
